I don't know in this case.

But I do know some of the moves are:

"If you don't throw yourself, your wrist/elbow/shoulder/whatever will be dislocated or broken."

And so the student, knowing this, saves themselves. IE the idea of rolling with the punches.

Which is to say, some moves are to be judged on the possible result, not the one you saw.

Whether that applies in this case, I don't know.
